Description

On our home page (using the "frontpage" theme), no tags are shown on the right hand side under "hot tags". I'm seeing a stack trace in the logs as shown:

Seems like if line 886 of HibernateUserManagerImpl were changed to use Number instead of Integer this issue could be fixed, but perhaps it would cause issues on dependent code.
